In sintesi

New snow and winds will create slabs in exposed areas. As the day progresses, watch for stiff or cracking snow. There is a layer of surface hoar that exists in some locations, dig down to see how new snow is bonding.

Great skiing will be found in sheltered treeline locations.

    Variable winds and new snow will have created wind slabs at ridge crests and on leeward features in the alpine and at treeline. Snowfall amounts and slab thickness are expected to be greater near the Columbia Icefields.

Avalanche Summary

No new avalanches have been observed or reported in the past few days.

Snowpack Summary

In sheltered areas, 5 to 10cm of new snow has fallen on top of a surface hoar layer. Below this is roughly 30 cm of soft snow and a generally supportive snowpack. We’re currently tracking a mid-November melt-freeze crust located in the mid-pack, though it has not shown any activity in our profiles.

Terrain and Travel Advice

  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Wind slabs are most reactive during their formation.
